摘要
A query that requests a filter attribute is received by a database server from a remote application server that is associated with at least one calculation scenario that includes calculation nodes having relational operators and calculation nodes having non-relational operators. The calculation nodes having relational or non-relational operators are optimized by a calculation engine model optimizer and the calculation nodes having relational operators are further optimized by a relational database optimizer. Thereafter, the operations defined by the optimized calculation nodes can be executed to result in a responsive data set. Next, the data set is provided to the application server by the database server.
